He always came in last. My experience is that the little pigs will rush in first, then the young sows, then the older sows, and if there is a boar he will hold back and come in once he's checked things out. And when he moves in he takes over.
The boar in the pic was solitary, he never mixed with the other hogs. All of the better boars I've killed have been that way.I shot him with a 53# Jeffery recurve, 2216 xx75 tipped with a woodsman. The arrow passed through except for the fletch and he bent the shaft when he fell on it. I shot him from a loc on in a creek bottom at the edge of an overgrown clearcut that was holding water due to beavers. I knew I had hit him well and heard him thrashing and gurgling about 50-75 yds out in the cut. Never any doubts about my gear selection, I knew it would do the job. Ive killed hogs with longbows recurves and selfbows from 45-65 lbs using carbon, aluminum and wood. Ive shot muzzy 3 blades, woodsmans, snuffers, and magnus 2 blades and stingers, razorheads, and a ribtec. They ALL worked when I put them in the right place.
